The state Office of the Superintendent of Public Instruction released a new measure of student performance Dec. 9, known as Student Growth Percentiles.

The percentiles are designed to measure the amount a student learns during one year and to show how students grow over time compared to their academic peers, students who earned similar scores on a prior test.

“We shouldn’t look at the data in just one way,” state Superintendent Randy Dorn said in a news release. “We need multiple measures. If a school is showing high growth from year to year, we should celebrate that. They’re doing exactly what they need to do to help kids be successful.”
